Description

The present invention relates to the structure of a frame for installing an aeration device installed in an aeration tank or the like of a sewage treatment facility.

Conventionally, in sewage treatment facilities, sewage is purified by aeration. The sewage to be treated is stored in an aeration tank, air is supplied from an aeration device installed in the aeration tank, and the sewage is purified by the activity of aerobic microorganisms. In this type of facility, when installing an aeration device in an aeration tank, it is necessary to provide a pedestal on the bottom of the aeration tank and support the aeration device at an appropriate height from the bottom. Prior art documents related to the frame structure of such a diffuser include, for example, the following Patent Document 1.

Japanese Patent Application Publication No. 2011-200769

By the way, the area and shape of the above-mentioned aeration tank vary depending on the facility, and in order to install an aeration device here, a pedestal must be constructed according to the size and shape of the bottom of the aeration tank. Here, when the material of the frame is metal, for example, metal members cut into appropriate lengths according to the dimensions of the aeration tank are welded at a factory, and the assembled state is transported to the aeration tank. It will be installed at the desired location within the tank. In other words, frames are custom-ordered each time depending on the situation of the installation target, but with this manufacturing method, it takes time to manufacture the frames at the factory, lengthening the construction period and increasing costs.In addition, manufacturing is outsourced. Another problem is that the manufacturing precision of the mount tends to vary depending on the technical level of the manufacturer.

In the invention described in Patent Document 1, a pedestal is configured by a column installed along the vertical direction and a rail-like member supported at the top of the column and extending in the horizontal direction. By subdividing and reducing the size of components such as rail-like members, and unifying the specifications of each component, it is possible to easily construct a frame that is suitable for the form of the aeration tank, regardless of the shape of the aeration tank. It is now possible to do so. By transporting a group of parts with the same specifications and smaller dimensions into the aeration tank and combining them as appropriate, a frame of appropriate dimensions to match the aeration tank is assembled on site.

However, even in such a mount described in Patent Document 1, there is still room for standardization of parts in that two types of members, a support and a rail-like member, are required as main components.

In view of these circumstances, the present invention seeks to provide a mount structure for an air diffuser that can suitably configure the mount for the air diffuser using components with a simple configuration.

The present invention is provided with a columnar main member having grooves extending in the longitudinal direction on opposing sides thereof, and by using a connecting aid, the grooves are arranged so that they face each other or are adjacent to each other.

The strut attachment part is provided in an adjustable attachment part that is slidable along the longitudinal direction of the main material as a strut, and connects the main material as a beam to an upper end of the main material as a strut. A post-beam connector configured to allow the post-beam connector to be provided may be provided.

In the frame structure of the air diffuser of the present invention, as the connection aid, the main members as a pair of beams are arranged so as to be stacked in directions orthogonal to each other in a plan view so that the grooves face each other. It is possible to provide a beam orthogonal joint that is configured to be able to join the main members as the pair of beams by being attached to the grooves.

In the frame structure of the air diffuser of the present invention, the connecting aids are attached to the grooves of the main members as a pair of beams arranged in a continuous direction, so that the main members as the pair of beams are arranged in continuous directions. A beam continuous connector configured to connect the beams to each other can be provided.

In the frame structure of the air diffuser of the present invention, in a cantilever structure portion in which the main member as a beam is cantilevered to the main member as a support, the connection aid is a groove portion of the main member as the beam; It can be provided with cantilever fittings that are respectively attached to the grooves of the main material as a support, and diagonal supports configured such that both ends in the longitudinal direction can be attached to the cantilever fittings, respectively.

In the frame structure of the air diffuser of the present invention, the connection aid is attached to the installation surface and the groove of the main material as a beam arranged along the horizontal direction, so that the main material as a beam A beam fixture configured to be able to fix the beam to the installation surface can be provided.

The frame structure of the air diffuser of the present invention includes, as the connection aid, a base part that can be attached to a groove located on the upper surface of the main material as a beam arranged along the horizontal direction, and a base part that holds the air diffuser. The air diffuser may be provided with a device mount that is configured to be able to hold the air diffuser on the upper surface of the main material as a beam.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 to 3 show an example of the form of the main material constituting the frame structure of the air diffuser according to the present invention. The main material 1 is a hollow part in the shape of a substantially quadrangular prism as shown in FIG. In this book, the two sides perpendicular to the longitudinal direction of a columnar main material are called "end faces" and the remaining surfaces extending along the longitudinal direction of the main material are called "side faces." Of the four side surfaces of the material, the two surfaces provided with the grooves will be referred to as the "first side surfaces" and the remaining two surfaces will be referred to as the "second side surfaces"). Both end faces are open, and the main member 1 has a tubular shape as a whole.

The groove portion 2 is a portion provided in each of the first side surfaces 3 facing each other so as to be recessed inward from the first side surface 3, and is located at the center of each first side surface 3 in the width direction. It is provided throughout. A flange 2a is provided at the edge of the groove 2 and protrudes toward the center of the first side surface 3 in the width direction.

The main material 1 is constructed by combining a pair of half-split bodies 4 as shown in FIG. An engaging portion 6 for combining the split bodies 4 with each other is provided along the longitudinal direction. That is, the half body 4 corresponds to a component obtained by dividing the main material 1 shown in FIGS. 1 and 2 at the engaging portion 6 provided on the second side surface 5 between the groove portions 2.

One half body 4 has two surfaces corresponding to the second side surface 5 (a surface obtained by dividing the second side surface 5 in half at the center in the width direction), one of which has an engagement surface that engages with the other. A first engaging portion 6a of the portions 6 is provided, and a second engaging portion 6b that engages with the first engaging portion 6a is provided on the other side. The first engaging portion 6a has a width at the end of one second side surface 5 provided on the half body 4 (in the second side surface 5 of the main material 1 configured by combining two half bodies 4). It is a plate-shaped portion that is folded inward from the center portion in the direction, and is provided over the entire length of the half body 4 in the longitudinal direction. The second engaging portion 6b is a plate-shaped portion that is folded inward from the end of the other second side surface 5 provided on the half body 4, similar to the first engaging portion 6a. , is further folded back from the end of the second side surface 5 to form a U-shaped cross section. The gap between the two plate-shaped portions that make up the U-shaped cross-sectional shape of the second engaging portion 6b is set to a size that allows exactly one plate that makes up the first engaging portion 6a to be sandwiched therebetween. ing.

As shown in FIGS. 1 and 2, when a pair of half bodies 4 are combined to form one main material 1, the first engaging portion 6a of one half body 4 is connected to the first engaging portion 6a of the other half body 4. The two halves 4 are connected so that the second engaging portion 6b of the other half body 4 contacts and the second engaging portion 6b of one half body 4 contacts the first engaging portion 6a of the other half body 4. Deploy. Then, the first engaging part 6a of the other half body 4 is sandwiched between the second engaging part 6b of the one half body 4, and the second engaging part 6b of the other half body 4 is inserted into the second engaging part 6b of the other half body 4. The first engaging portion 6a of the split body 4 is sandwiched between the two to engage with each other. The plate-shaped members constituting the first engaging part 6a and the second engaging part 6b are provided with ribs 6c and 6d along the longitudinal direction at mutually corresponding positions, and the half bodies 4 are assembled together. In this state, the ribs 6c and 6d fit into each other, thereby increasing the strength of engagement.

When combining a pair of half-split bodies 4, the other half-split body 4 is moved to slide in the longitudinal direction with respect to one half-split body 4, and each half-split body 4 is moved so as to slide in the longitudinal direction. It is only necessary to sandwich one engaging portion 6a.

The main material 1 having such a configuration can be formed to have any dimension in the longitudinal direction, or can be cut at any position in the longitudinal direction, and used as a member of an appropriate length in constructing a frame to be described later. can. In the main material 1 of this embodiment, the groove portion 2 and the engaging portion 6 are provided over the entire length in the longitudinal direction as described above, so all cross sections perpendicular to the longitudinal direction of the main material 1 are as shown in FIG. It has the same shape as the end face shown in . The main material 1 can be manufactured using various materials and manufacturing methods. For example, it can be manufactured using a method called roll forming, in which a metal plate is used as a material and is bent.

Construction of a frame for an air diffuser using the main material 1 as described above will be explained. As described below, various connection aids with simple configurations (post fixing tool 20, post-beam connectors 21, 22, beam orthogonal connectors 23, continuous beam connectors 24, 25, cantilever mounts 26, diagonal By fixing the main material 1 to the installation surface using support materials 27) as appropriate and further combining the main materials 1 vertically and horizontally, a frame 100 as shown in FIG. 4 is assembled, for example, and the air diffuser 200 is attached thereto. can be supported. In the frame 100, the main member 1 functions as a beam extending in the horizontal direction and as a support column extending in the vertical direction.

For convenience, in this specification, regardless of the original definition of "beam" or "column" in a building, the main material installed along the horizontal direction is referred to as "beam", and the main material installed along the vertical direction is referred to as "beam". The materials are called "posts" as appropriate. In addition, in the following, expressions such as "along the horizontal direction" and "along the vertical direction" will often appear regarding members and the surfaces formed by the members, but these do not necessarily mean that the orientation of the member, etc. is horizontal or vertical. does not mean an exact match. For practical purposes as a frame or for people's general sense, it means close to the horizontal or vertical direction to the extent that it can be expressed as horizontal or vertical. The same applies to the expression "orthogonal."

When combining the main materials 1 using a connecting aid, as described below, the main materials 1 to be combined are arranged so that the grooves 2 face each other or are adjacent to each other, and the grooves 2 are Connect them using an appropriate connecting aid. Here, "the grooves 2 face each other or are adjacent to each other" means that the first side surfaces 3 having the grooves 2 of the pair of main members 1 related to the connection are connected, as shown in each figure explained below. are facing each other, or the grooves 2 of the pair of main members 1 involved in the connection are arranged continuously in the longitudinal direction, or the surfaces formed by the first side surfaces 3 of the pair of main members 1 involved in the connection intersect with each other. It refers to a positional relationship in which the grooves 2 provided on each first side surface 3 intersect with each other. The connection aids connect the main members 1 to each other by being connected to the pair of grooves 2 having such a positional relationship. Further, when fixing the main member 1 as a support to an installation surface or when attaching the diffuser 200 to the main member 1 as a beam, a connecting aid is attached to the groove 2 and used.

(I) Installation of pillars

When fixing the main member 1 as a support to an installation surface such as the bottom of an aeration tank on which the pedestal 100 is installed, a connecting aid (post fixing tool) 20 as shown in FIG. 5 is used, for example. The pillar fixing device 20 includes a rectangular plate-shaped base portion 20a that forms a surface along the horizontal direction in the installed state, and two pieces that protrude upward from the middle portion in the longitudinal direction of each opposing long side of the base portion 20a. It is provided with a plate-shaped attachment part 20b. Fixing holes 20c are provided at positions near both ends of the base portion 20a in the longitudinal direction so as to vertically penetrate through the base portion 20a.

The pair of attachment parts 20b face each other across the base part 20a in the width direction. The width of each attachment portion 20b and the distance between the attachment portions 20b correspond to the groove portions 2 provided on the two first side surfaces 3 of the main material 1. It can be inserted into each groove 2 provided on the side surface 3 at the same time. Here, the width of the attachment part 20b is such that it can be inserted into the groove part 2, but it is set larger than the interval between the collar parts 2a provided at the edges of the groove part 2. Further, the distance between the fixing holes 20c is set wider than the distance between the second side surfaces 5 of the main material 1, and the fixtures attached to the fixing holes 20c prevent the main material 1 from being attached to the mounting portion 20b. There is no such thing.

Each mounting portion 20b is provided with two mounting holes 20d on the upper and lower sides so as to pass through the plate-shaped mounting portion 20b in the thickness direction (the direction in which the mounting portions 20b face each other). A threaded groove is formed on the inner peripheral surface of the mounting hole 20d, so that a bolt 10 as a fastener can be inserted and tightened as described later.

In order to fix the main member 1 as a support to the installation surface, first, holes for fixing tools (components for fixing the frame 100 to the installation surface, such as anchor bolts) are provided in the installation surface. This hole is provided so as to correspond to the position of the fixing hole 20c of the post fixture 20. Place the column fixing tool 20 on the installation surface so that the fixing hole 20c of the base part 20a overlaps with this hole position, and as shown in FIG. 6, insert the anchor bolt 7 as a fixing device into the fixing hole 20c and tighten it to fix the column. Fix the tool 20 to the installation surface.

In this state, the pair of attachment parts 20b protrude from the installation surface. The main material 1 is arranged along the vertical direction with the end surface of the main material 1 facing downward, with each of the protruding attachment parts 20b being inserted into the two grooves 2, respectively. Bolts 10 as fasteners are inserted into each mounting hole 20d of the mounting portion 20b inserted into the groove 2 and tightened. At this time, if necessary, a washer 8 with a diameter larger than the interval between the flanges 2a provided in the groove 2 is used as a seating surface (note that among the washers 8 shown in FIG. The washer is a spring washer, and the washer labeled 8b is the washer that serves as the seat surface.) On the other hand, the width of the attachment part 20b inserted into the groove part 2 is set larger than the interval between the collar parts 2a provided in the groove part 2. When the bolt 10 is tightened, the flange 2a provided in the groove 2 is sandwiched between the washer 8b serving as a seat surface and the attachment part 20b, thereby attaching the main member 1 to the column fixture 20. In this way, as shown in the lower part of FIG. 6, the main member 1 as a support is fixed to the installation surface by the support fixture 20.

(II) Joining pillars and beams (1)

When joining the main member 1 as a beam to the main member 1 as a support, a connecting aid (post-beam connector 21) as shown in FIG. 7 is used, for example. The post-beam connector 21 is a rectangular plate-shaped component bent in an L-shape so as to form two mutually perpendicular surfaces, and one mounting hole is provided in the beam mounting portion 21a forming one surface. Two mounting holes 21d are provided in the support mounting portion 21c, which is the other surface of the support mounting portion 21b, so as to pass through the beam mounting portion 21a or the support support mounting portion 21c in the thickness direction, respectively. In the column attachment part 21c, the two attachment holes 21d are lined up along the direction in which the column attachment part 21c extends with respect to the beam attachment part 21a.

In order to join the main member 1 as a beam to the main member 1 as a support, for example, as shown in FIG. 8, two post-beam joints 21 are attached to the groove 2 of the main member 1 as a beam. Each post-beam connector 21 is attached to the same groove 2 (groove 2 located on the lower side in the installed state) of the two grooves 2 provided in the main material 1, on the first side surface 3 where the groove 2 is provided. The beam attachment portions 21a are in contact with the two beam attachment portions 21a, and the two column beam connectors 21 are arranged in such a direction that the column attachment portions 21c face each other (regarding the extending direction of the groove portion 2, the two column attachment portions 21a are attached to the inside of the two beam attachment portions 21a). 21c). The pillar mounting portions 21c of the two pillar-beam connectors 21 are shaped to protrude from the first side surface 3 of the main member 1 as a beam in a plane along a direction perpendicular to the longitudinal direction of the main member 1. . Here, the main material 1 as a support is joined by sandwiching it between the two support support attachment parts 21c.

The main member 1 as a support is located on the lower side of the main member 1 as a beam, with its upper end surface in contact with the first side surface 3 of the main member 1 as a beam. The first side surfaces 3 are adjacent to each other on both sides of the main member 1 serving as a support, and the grooves 2 provided on the first side surfaces 3 are perpendicular to each other in a form that intersects with each other. The first side faces 3 on both sides of the main member 1 as a support are in contact with the support installation parts 21c of the support beam connectors 21, respectively, and the bolts 10 as fasteners inserted into the attachment holes 21d and the grooves 2 are attached to the support as a support. The main member 1 and the post-beam connector 21 are fixed to each other. The beam mounting portions 21a of the two pillar-beam connectors 21 are in contact with the first side surface 3 located below the main member 1 as a beam, and a bolt as a fastener is inserted into the mounting hole 21b and the groove portion 2. 10, the main member 1 as a beam and the column beam connector 21 are fixed to each other.

For joining, for example, first insert bolts 10, washers 8, and nuts 9, which are fasteners, into the respective mounting holes 21b and 21d provided in the beam attachment part 21a and the column attachment part 21c of the two pillar-beam connectors 21, respectively. Temporarily fasten it. The bolt 10, washer 8, and nut 9 are attached to the beam attachment part 21a and the column attachment part 21c, for example, so that the head of the bolt 10 is located on the groove 2 side of the main member 1.

In this state, first, among the fasteners temporarily fastened to the beam attachment part 21a, pass the part (the head of the bolt 10) that protrudes toward the main material 1 as a beam into the groove 2 of the main material 1 as a beam, and then The beam connector 21 is placed on the main material 1 as a beam. Here, the bolt 10 to be inserted into the groove 2 has dimensions such that the head does not rotate in the groove 2 and does not fall off from the groove 2 in the axial direction, that is, the minimum diameter of the head is equal to or less than the width of the groove 2, and A bolt with dimensions larger than the interval between the flanges 2a provided in the groove 2 and whose maximum diameter is larger than the width of the groove 2 is used.

Next, among the fasteners temporarily fastened to the strut attachment part 21c, attach the strut so that the part (the head of the bolt 10) that protrudes toward the main material 1 as a strut passes through the groove 2 of the main material 1 as a strut. The main material 1 is slid and arranged between the pillar attachment parts 21c. In this state, each fastener (nut 9) of the beam attachment part 21a and the column attachment part 21c is tightened. Note that, if necessary, each fastener may further include a washer as a seat surface to prevent it from coming off. Further, the orientation of each fastener shown here may be reversed.

In this way, the two pillar-beam connectors 21 have their beam attachment portions 21a attached to the grooves 2 of the main material 1 serving as a beam, and the column attachment portions 21c attached to the grooves 2 of the main material 1 serving as a column. As shown in the upper part of FIG. 6, the main member 1 as a support and the main member 1 as a beam are joined to each other in a manner perpendicular to each other. The main members 1 to be joined to each other are arranged in a positional relationship such that the surfaces formed by the first side surfaces 3 are orthogonal to each other, and the grooves 2 provided on each first side surface 3 are orthogonal to each other, and the positions where the grooves 2 touch each other are A column beam connector 21 is attached to the column. The main member 1 as a beam is joined to the upper end portion of the main member 1 as a support with the two first side surfaces 3 provided with the grooves 2 facing upward and downward.

(III) Joining pillars and beams (2)

When the main member 1 as a beam is joined to the main member 1 as a support and the height is desired to be adjusted, a connection aid (post-beam joint) 22 as shown in FIG. 9, for example, is used. In the air diffuser mount 100 as shown in FIG. 4, the air diffuser 200 is installed on the main member 1 as a beam, but the orientation of the main member 1 on which the air diffuser 200 is installed is as close to horizontal as possible. This is desirable. The air bubbles supplied from the air diffuser 200 are released as air bubbles from the top surface of the air diffuser 200, which has a rectangular shape, and move upward. At this time, if the air bubble distribution in the horizontal section is uneven, the air bubble distribution will be affected. It is easy for bubbles to coalesce in areas where the bubbles are dense, resulting in a decrease in the surface area relative to the volume of the bubbles, resulting in a decrease in oxygen dissolution efficiency. In order to efficiently perform aeration by the aeration device 200, the aeration device 200 is installed horizontally and air is supplied from the horizontal surface to equalize the distribution of bubbles rising in the liquid and reduce the bubble diameter. It is better to keep it. On the other hand, the installation surface on which the pedestal 100 is installed varies, and the height may vary depending on the location. In such a case, the beam can be supported horizontally by changing the height of the support depending on the location, but it would be more convenient if the height at which the beam is attached to the support could be easily adjusted.

The post-beam connector 22 is designed to be able to adjust the installation height of the main material 1 as a beam relative to the main material 1 as a support when joining the main material 1 as a beam to the main material 1 as a support. It is a part. As shown in FIG. 9, the column-beam connector 22 includes a beam attachment portion 22a and an adjustment attachment portion 22b. The adjustment attachment portion 22b is a plate-shaped member formed to have three surfaces that are orthogonal to each other, and the three surfaces that make up the adjustment attachment portion 22b extend in the same longitudinal direction. That is, the cross section of the adjustment attachment portion 22b perpendicular to the longitudinal direction has a U-shape or a U-shape due to the three surfaces.

Of the three surfaces constituting the adjustment attachment portion 22b, the two opposing sides are configured as a strut attachment portion 22c to which the main material 1 as a strut is attached, and two surfaces are provided at the center in the width direction of each side. A mounting hole 22d is provided so as to penetrate the column mounting portion 22c in the thickness direction. In each strut attachment portion 22c, two attachment holes 22d are arranged in the longitudinal direction of the strut attachment portion 22c.

The remaining one of the three surfaces constituting the adjustment attachment portion 22b functions as a connecting portion 22e that connects the column attachment portions 22c at appropriate intervals. As will be described later, the post-beam connector 22 is installed so that the two post attachment parts 22c are in contact with the first side surface 3 of the main member 1 serving as a support, but in this case, the connecting part 22e is By connecting the parts 22c at appropriate intervals, the three sides forming the adjustment attachment part 22b cover the three sides of the main member 1 in a sleeve-like manner, thereby allowing the column beam connector 22 to be attached to the main member 1. It can be installed smoothly.

The beam attachment portions 22a are a pair of plate-shaped members, and form a surface perpendicular to the plane formed by the column attachment portion 22c from one end in the longitudinal direction of the column attachment portion 22c, and the pair of column attachment portions 22c are opposed to each other. It is provided so as to protrude outward in the direction in which it is directed. One attachment hole 22f is provided in each central portion of the beam attachment portions 22a.

In other words, the post-beam connector 22 shown here has the post-beam connector 21 shown in FIG. It is equivalent to parts connected at appropriate intervals by 22e.

For joining, for example, first, bolts 10, washers 8, and nuts 9, which are fasteners, are temporarily fastened to each mounting hole 22d provided in the pair of pillar mounting portions 22c of the pillar-beam connector 22, respectively. FIG. 9 shows a state in which each fastener is attached to the attachment hole 22d so that the head of the bolt 10 is located on the groove 2 side of the main member 1 as a beam (inside the opposing column attachment part 22c). , the orientation of the bolt 10 and nut 9 may be reversed.

In this state, the fasteners (heads of the bolts 10) protrude inside the pair of opposing strut mounting portions 22c. Insert the fasteners protruding here into the two grooves 2 provided in the main member 1 as a support column, and adjust the attachment portions 22b forming three surfaces to cover three sides of the support beam connector 22 (support support). The post-beam connector 22 is slid onto the main member 1 in such a manner that the mounting portions 22c are in contact with the two first side surfaces 3, and the connecting portion 22e is in contact with the one second side surface 5. At this time, the column-beam connector 22 is oriented such that the beam attachment portion 22a is located upward (above in the final installation direction). Since the post-beam joint 22 can be freely slid along the longitudinal direction with respect to the main member 1, each The fastener attached to the attachment hole 22d is tightened to fix the column beam connector 22 to the main member 1.

Subsequently, as shown in FIG. 10, the main material 1 as a beam is joined here. When the pillar-beam connector 22 is attached to the main member 1 as a column, a pair of beam attachment parts 22a are located at the top of the pillar-beam connector 22, so the main member 1 as a beam is fixed there. do.

Insert the heads of bolts 10 in a number (two) corresponding to the number of mounting holes 22f provided in the beam mounting part 22a of the post-beam connector 22 into one groove 2 of the main material 1, and The groove portion 2 is made to project outward from the groove portion 2. The tips of the bolts 10 are inserted into the mounting holes 2f of the beam mounting portion 22a, and the washers 8 and nuts 9 are mounted there. In this state, the main material 1 as a beam can be freely slid along the direction of the groove 2 with respect to the post-beam connector 22, so the main material 1 as a beam can be moved appropriately relative to the post-beam connector 22. With the main member 1 supported at a certain position, each fastener attached to the beam attachment part 22a is tightened to fix the main member 1 as a beam to the column beam connector 22.

In this way, the post-beam connector 22 has a pair of beam attachment parts 22a attached to the grooves 2 of the main material 1 as a beam, a pair of column attachment parts 22c to the grooves 2 of the main material 1 as a support, and this As a result, as shown in FIG. 11, the main member 1 serving as a support and the main member 1 serving as a beam are joined to each other in a perpendicular manner. The main members 1 to be joined to each other are located at positions slightly apart from each other in a positional relationship such that the surfaces formed by the first side surfaces 3 are orthogonal to each other, and the straight lines formed by the grooves 2 provided on each first side surface 3 are orthogonal to each other. The pillar-beam connectors 22 are installed so as to connect them. The main member 1 as a beam is joined to the upper end portion of the main member 1 as a support with the two first side surfaces 3 provided with the grooves 2 facing upward and downward. Here, since the height at which the post-beam connector 22 is attached to the main member 1 as a support can be adjusted, the main member 1 as a beam can be supported at an appropriate height.

(IV) Orthogonal connection between beams

When joining the main members 1 as beams so that they are perpendicular to each other, a connecting aid (beam orthogonal joining tool) 23 as shown in FIGS. 12 to 14 is used, for example. The beam orthogonal joint 23 is a plate-like member having an octagonal shape as a whole, and mounting holes 23a are provided at the corners at four vertices of a square. The four mounting holes 23a are arranged such that the distance between the two diagonal corners of a square is greater than the width of the first side surface 3 of the main material 1. With this beam orthogonal joining tool 23 in between, as shown in FIG. 14, the two main members 1 are joined in such a way that they are stacked one above the other so that the grooves 2 face each other.

The main members 1 as beams are joined to each other with the first side surfaces 3 provided with the grooves 2 facing upward and downward. For joining, first, as shown in FIG. 12, two bolts 10, which are fasteners, are passed through the groove 2 of one main member 1 on the side to be joined to the other main member 1. At this time, the bolt 10 is arranged so that the head of the bolt 10 is located within the groove 2 and the tip of the bolt 10 projects outward from the groove 2.

The tip of the bolt 10 protruding from the groove 2 is passed through the mounting hole 23a of the beam orthogonal joint, and the washer 8 and nut 9, which are fasteners, are attached and tightened. Here, the mounting holes 23a through which the bolts 10 are passed are two diagonally located mounting holes 23a among the four mounting holes 23a forming the four vertices of the square.

Subsequently, as shown in FIG. 13, two bolts 10 are passed through the groove 2 of the other main member 1 on the side to be joined to one main member 1. The bolt 10 is arranged so that the head is located within the groove 2 and the tip protrudes outward from the groove 2. The tips of these bolts 10 are passed through the remaining attachment holes 23a of the beam orthogonal joint, and the fasteners 8 and nuts 9 are attached and tightened.

Here, as described above, the distance between the four mounting holes 23a, which are diagonal to each other, is set to be larger than the width of the first side surface 3 of the main material 1. As a result, when one main material 1 is attached to the two diagonal mounting holes 23a and the other main material 1 is further placed, the two mounting holes 23a are connected to the other main material 1. Since they are located on the outside in the width direction, the fasteners attached to the two attachment holes 23a do not interfere with the other main member 1. Also, when attaching the other main material 1 to the remaining two mounting holes 23a, since the two mounting holes 23a are located on the outside in the width direction of one main material 1, 1 will not interfere with the installation of fasteners.

In this way, the beam orthogonal connector is sandwiched between the main members 1 as beams arranged so that the grooves 2 face each other, and a part of the mounting hole 23a is inserted into the groove 2 of one of the main members 1. Another part of the mounting hole 23a is attached to the groove 2 of the other main member 1, and as a result, as shown in FIG. join.

Here, we have illustrated the case where four mounting holes 23a are provided in the beam orthogonal joint to form the four vertices of a square, but when joining the main members 1 as beams in this way, the mounting holes 23a The number of installations may be greater than this. At least four mounting holes should be provided so that they are diagonal to each other and the distance between them is greater than the width of the main material 1. For example, in addition to the four mounting holes, Another attachment hole may be provided outside the attachment hole. Further, the arrangement of the four mounting holes does not necessarily have to be square.

(V) Connection between beams (1)

When it is desired to connect the main members 1 as beams in the longitudinal direction, a connecting aid (beam continuous connector) 24 as shown in FIG. 15 is used, for example. The continuous beam connector 24 is an elongated plate-like member, and a total of four mounting holes 24a, two at each end in the longitudinal direction, are provided so as to penetrate the continuous beam connector 24 in the thickness direction. There is. The four attachment holes 24a are arranged along the longitudinal direction of the beam continuous connector 24. The width of the continuous beam connector 24 is set to be wider than the distance between the flanges 2a provided at the edges of the groove 2 of the main material 1, and narrower than the width of the groove 2 other than the flanges 2a. The beam continuous connector 24 can be inserted into the groove 2 of the main material 1 so that the longitudinal direction and the width direction are aligned. A threaded groove for inserting and tightening the bolt 10 as a fastener is formed on the inner circumferential surface of the mounting hole 24a.

For joining, the ends of the beam continuous connectors 24 are respectively inserted into the grooves 2 of the first side surfaces 3 located below the two main members 1, and the end surfaces of the main members 1 are brought into contact with each other. In this state, the attachment hole 24a of the beam continuous connector 24 is exposed in the groove 2 on the lower side of the two main members 1. In one main member 1, two mounting holes 24a provided at one end of the beam continuous connector 24 are exposed, and in the other main member 1, two mounting holes 24a provided at the other end of the beam continuous connector 24 are exposed. The two mounting holes 24a are exposed. Bolts 10 as fasteners are inserted into each of these mounting holes 24a while appropriately sandwiching washers 8, and then tightened.

In this way, the beam continuous connector 24 is inserted into the groove 2 of the pair of main members 1 so as to straddle the pair of main members 1 disposed in a continuous direction in the longitudinal direction, and is attached to one end side. A part of the hole 24a is connected to one main member 1, and another mounting hole 23a is connected to the other main member 1, so that the main members 1 as two beams are connected to each other in a continuous manner in the longitudinal direction. Connect. The beam continuous connector 24 is set to a dimension that takes into account the physical properties of the material and maintains sufficient strength as a component of the frame. Appropriately supports the applied load.

(VI) Connection between beams (2)

In the above (V), connection of the main members 1 as beams in a place where the main members 1 as pillars are not installed has been explained. If it is desired to connect the main members 1 as beams in the longitudinal direction at a location where the main members 1 as supports are installed, a connecting aid (beam continuous connector) 25 as shown in FIG. 16 is used, for example. The continuous beam connector 25 is an elongated plate-like member, and a total of four mounting holes 25a, two at each end in the longitudinal direction, are provided so as to penetrate through the continuous beam connector 25 in the thickness direction. There is. The four attachment holes 25a are arranged along the longitudinal direction of the beam continuous connector 25. The width of the continuous beam connector 25 is set to be wider than the distance between the flanges 2a provided at the edges of the groove 2 of the main material 1, and narrower than the width of the groove 2 other than the flanges 2a. The beam continuous connector 25 can be inserted into the groove 2 of the main material 1 so that the longitudinal direction and the width direction are aligned. A threaded groove for inserting and tightening the bolt 10 as a fastener is formed on the inner circumferential surface of the mounting hole 25a.

As described above, the continuous beam connector 25 is a member having almost the same configuration as the continuous beam connector 24 shown in FIG. 15, but the longitudinal dimension is slightly different from the continuous beam connector 24 in FIG. They are different in size and have dimensions that match the dimensions of the main member 1 as a support and the support beam connectors 21, 22 (FIGS. 7 to 11). Specifically, among the four mounting holes 25a, the distance between the two mounting holes 25a located on the inner side in the longitudinal direction is such that the distance between the two mounting holes 25a located on the inside in the longitudinal direction is such that the distance between the two mounting holes 25a is such that the distance between the two mounting holes 25a located on the inner side in the longitudinal direction is such that the distance between the two mounting holes 25a is such that the distance between the two mounting holes 25a located on the inner side in the longitudinal direction is such that the distance between the two mounting holes 25a that are located on the inner side in the longitudinal direction is such that the distance between the two mounting holes 25a that are located on the inner side in the longitudinal direction is such that the distance between the two mounting holes 25a that are located on the inner side in the longitudinal direction is such that the distance between the two mounting holes 25a that are located on the inside in the longitudinal direction is such that the distance between the two mounting holes 25a that are located on the inside in the longitudinal direction is such that the distance between the two mounting holes 25a that are located on the inner side in the longitudinal direction is such that the The distance between the mounting holes 21b of the beam attachment portions 21a of the post-beam joint 21 is set to match the distance between the mounting holes 21b of the post-beam joint 21 (here, the post-beam joint 21 of FIGS. 7 and 8 is illustrated, but the distance shown in FIG. ~The distance between the mounting holes 22f in the beam mounting portion 22a of the post-beam connector 22 in FIG. (can be installed using the same procedure as above).

For joining, the ends of the continuous beam joints 25 are respectively inserted into the grooves 2 of the first side surfaces 3 located below the two main members 1, and the end surfaces of the main members 1 are brought into contact with each other. In this state, the attachment hole 25a of the beam continuous connector 25 is exposed in the groove 2 on the lower side of the two main members 1. In one main member 1, two mounting holes 25a provided at one end of the beam continuous connector 25 are exposed, and in the other main member 1, two mounting holes 25a provided at the other end of the beam continuous connector 25 are exposed. Two mounting holes 25a are exposed.

Here, the end face of the main member 1 as a column with the column-beam connectors 21 attached to both first side surfaces 3 of the upper end is attached, and the two mounting holes located on the inner side in the longitudinal direction of the beam-continuous connectors 25 are attached. 25a and the mounting holes 21b provided in the pair of beam mounting portions 21a are aligned. In this state, bolts 10 as fasteners are inserted into each of the four mounting holes 25a and tightened. At this time, regarding the two mounting holes 25a located inside in the longitudinal direction of the beam continuous connector 25, the beam attachment part 21a of the column beam connector 21 functions as a seat surface, so the washer 8b as a seat surface is unnecessary. Regarding the two mounting holes 25a located on the outside, since they are tightened into the grooves 2 of the main material 1 to be connected where there is no column-beam connector 21, the washers 8b serving as the seat surfaces are tightened as necessary. use.

In this way, the beam continuous connector 25 is inserted into the groove 2 of the pair of main members 1 so as to straddle the pair of main members 1 disposed in a continuous direction in the longitudinal direction, and is attached to one end side. A part of the hole 25a is connected to one main member 1, and another mounting hole 23a is connected to the other main member 1, so that the main members 1 as two beams are connected to each other in a continuous manner in the longitudinal direction. Connect.

Here, we have illustrated the case where the beam continuous connectors 24 and 25 are provided with four attachment holes 24a and 25a, respectively, but when joining the main members 1 as beams in this way, the number of attachment holes The number of installations may be two or more along the longitudinal direction, and the number may be more or less than four.

(VII) Installation of cantilever beams

In the frame 100 as shown in FIG. 4, when a heavy object such as the air diffuser 200 is installed on the main member 1 as a beam, the main member 1 as the beam is attached to the supported object (air diffuser 200) in the longitudinal direction. From the viewpoint of structural mechanics, it is most desirable to be joined to the main member 1 as a support on both sides. However, depending on the conditions of the installation surface, etc., it may not always be possible to install the main member 1 as a support in such a position. In such a case, the main member 1 as a beam can be supported by a cantilever with respect to the main member 1 as a support.

When the main member 1 as a beam is cantilevered to the main member 1 as a support, use cantilever fittings 26 and diagonal supports 27 as shown in FIGS. 17 to 20, for example, as connection aids. .

As shown in FIG. 17, the cantilever fixture 26 has a rectangular plate-shaped base 26a, and is bent and stands up from the middle of one long side of the base 26a, and is perpendicular to the plane formed by the base 26a and extends from the base. A plate-shaped attachment portion 26b is provided which forms a surface along the longitudinal direction of the portion 26a. A total of two mounting holes 26c are provided at both ends of the base portion 26a in the longitudinal direction so as to penetrate through the base portion 26a in the thickness direction. One mounting hole 26d is provided in the center of the mounting portion 26b so as to pass through the mounting portion 26b in the thickness direction.

A total of two attachment holes 27a are provided on one of the two mutually perpendicular surfaces at both ends in the longitudinal direction so as to penetrate the member in the thickness direction.

In a cantilever structure in which the main member 1 serving as a beam is cantilevered to the main member 1 serving as a support, the cantilever fittings 26 are provided, one each for the main member 1 serving as a beam and the main member 1 serving as a support. Two cantilever fixtures 26 are attached, and a diagonal support member 27 is attached so as to pass between these two cantilever fixtures 26. Thereby, the load applied to the main member 1 as a cantilevered beam can be transmitted to the main member 1 as a support via the diagonal support member 27, and the main member 1 as a beam can be suitably supported.

To attach the diagonal support member 27 to a portion of the cantilever structure, first, as shown in FIGS. 17 and 18, cantilever fixtures 26 are attached to the main member 1 as a support and the main member 1 as a beam, respectively. The mounting position of the cantilever fixture 26 on the main member 1 as a beam is the first side surface 3, which is below the portion that projects as a cantilever from the main member 1 as a support. The mounting position of the cantilever fixture 26 on the main member 1 as a support is the first side surface 3 on the side facing the main member 1 protruding as a cantilever.

Bolts 10 as fasteners are inserted into the grooves 2 of the first side surface 3 of these main members 1 in the number of attachment holes 26c (two each) provided in the base portion 26a of each cantilever attachment 26. The bolt 10 is oriented such that the head is located within the groove 2 and the tip protrudes outward from the groove 2. The tips of the bolts 10 protruding from the groove 2 are passed through the mounting holes 26c provided in the base portion 26a of the cantilever mount 26, and then a washer 8 and a nut 9 as fasteners are attached and tightened. In this way, the cantilever fixtures 26 are attached to the main member 1 as a beam and a support, respectively.

As shown in FIG. 19, each of the cantilever fittings 26 attached to the main member 1 as a beam and the main member 1 as a support has a mounting portion 26b protruding from the first side surface 3 of each main member 1. state. A diagonal support member 27 is attached here. Using attachment holes 27a provided at both ends of the diagonal support 27 in the longitudinal direction, the ends of the diagonal support 27 are connected to the two cantilever fixtures 26, respectively. Among the mounting holes 27a of the diagonal support member 27, one position is attached to the mounting hole 26d of the cantilever fixture 26 attached to the main member 1 as a support, and the other position is attached to the main member 1 as a beam. Align them with the mounting holes 26d of the cantilever mount 26, respectively. The bolt 10 is inserted so as to pass through the mounting hole 27a provided in the diagonal support member 27 and the mounting hole 26d of the cantilever mount 26, and the washer 8 and nut 9 are attached and tightened. In addition, when attaching the diagonal support member 27, temporarily fasten the fastener of the mounting hole 26c at the attachment portion 26b of at least one of the two cantilever fixtures 26, and adjust the length of the diagonal support member 27. It is preferable to slide the cantilever fixture 26 along the groove 2 and adjust the position accordingly. In this way, as shown in FIG. 20, the diagonal support member 27 is attached via the cantilever fixture 26 to the main member 1 serving as the pillar and beam that constitute the cantilever structure.

(VIII) Installing the beam on the installation surface

Depending on the conditions of the installation surface, such as the height of the installation surface varying depending on the location, it may be desirable to fix the main material 1 as a beam to the installation surface without using a support. In such a case, for example, a connecting aid (beam fixture) 28 as shown in FIG. 21 is used. The beam fixture 28 is a rectangular plate-like member, and fixing holes 28a are provided at positions near both ends in the longitudinal direction so as to vertically pass through the beam fixture 28, respectively. Attachment holes 28b are provided at the intermediate portion in the longitudinal direction of the beam fixture 28 and at positions near both ends in the width direction so as to vertically penetrate through the beam fixture 28, respectively. The interval between the fixing holes 28a is set wider than the width of the first side surface 3 of the main material 1, and when the beam fixture 28 is attached to the main material 1 using the attachment holes 28b as described later, The main material 1 does not interfere with attachment of the fixture to the fixing hole 28a.

When fixing the main material 1 as a beam to the installation surface, first insert a fastener into the groove 2 provided on one first side surface 3 of the main material 1 (the first side surface 3 located on the lower side in the installed state). As many bolts 10 as there are mounting holes 28b provided in the beam fixture 28 (two) are passed through the bolts 10. The bolt 10 is oriented such that the head is located within the groove 2 and the tip protrudes outward from the groove 2. The tips of the bolts 10 protruding from the groove 2 are passed through the mounting holes 28b provided in the beam fixture 28, and then the washers 8 and nuts 9 as fasteners are attached and tightened. In this way, the beam fixture 28 is attached to the groove 2 of the main material 1 serving as a beam.

The main material 1 is installed horizontally on an installation surface provided with holes for fixing devices (for example, anchor bolts), with the first side surface 3 to which the beam fixing device 28 is attached facing downward (see FIG. 22). . Place the beam fixing tool 28 together with the main material 1 on the installation surface so that the fixing hole 28a overlaps with the fixing hole position, insert the anchor bolt 7 as a fixing device into the fixing hole 28a, and tighten it to tighten the beam fixing tool 28. Attach to the installation surface. In this way, the main material 1 as a beam is fixed to the installation surface by the beam fixture 28.

(IX) Installation of air diffuser

When disposing the air diffuser 200 on the frame 100 (see FIG. 4) assembled using the various connection aids as described above, for example, a The air diffuser 200 is attached using a connecting aid (equipment attachment) 29 as shown in 23.

The device mount 29 is a plate-shaped member formed by bending a single rectangular plate as shown in FIG. A holding portion 29b is provided. The base portion 29a and the holding portion 29b are parallel to each other, and the base portion 29a and the holding portion 29b are connected to each other via a stepped portion 29c. That is, a stepped portion 29c rises from one side of the rectangular base portion 29a so as to form a plane perpendicular to the base portion 29a and is bent, and the stepped portion 29c extends toward the opposite side from the base portion 29a at its tip side. It is bent to form a plane (holding part 29b) parallel to the base part 29a. The device mount 29 is attached to the upper surface of the main member 1 as a beam in such a manner that the plane formed by the base part 29a and the holding part 29b is along the horizontal direction, and the holding part 29b is positioned above the base part 29a. .

A mounting hole 29d is provided in the center of the base portion 29a so as to pass through the base portion 29a in the thickness direction. The attachment hole 29d is formed in the shape of a long hole, and is provided so that its longitudinal direction is along the direction that connects the base portion 29a and the holding portion 29b.

The air diffuser 200 is a thin rectangular device with a rectangular frame as shown in FIGS. 4 and 24. In the device mounting fixture 29, the distance between the plane along the lower surface of the base portion 29a and the plane along the lower surface of the holding portion 29b is set equal to the thickness of the frame of the air diffuser 200, and as described below. In addition, the frame of the air diffuser 200 can be held between the holding portion 29b and the main member 1 with the base portion 29a attached to the main member 1 as a beam.

The air diffuser 200 is disposed with respect to the pedestal 100 at both ends in the longitudinal direction in such a manner that the width direction of the air diffuser 200 is along the longitudinal direction of the main member 1 as a beam. Then, both sides in the width direction of the end portion of the air diffuser 200 placed on the main member 1 are attached to the main member 1 by device mounting tools 29 . That is, a total of four device attachments 29 are attached to one air diffuser 200, two at each end in the longitudinal direction.

To fix the air diffuser 200 to the main material 1 as a beam, first insert the bolts 10 as fasteners into the grooves 2 provided in the first side surface 3 above the main material 1 to be installed. 1 (2 per one diffuser 200 attached to one main material 1) through the number of attachment holes 29d of the device attachment 29 attached to one main material 1. Each bolt 10 is oriented such that the head is located within the groove 2 and the tip protrudes outward from the groove 2. The tip of the bolt 10 protruding from the groove 2 is passed through a mounting hole 29d provided in the base 29a of the device mount 29, and then a washer 8 and a nut 9 as fasteners are attached. At this time, the fasteners are temporarily fastened to the main material 1 and the device fixture 29.

The air diffuser 200 is placed at an appropriate position with respect to the main material 1 as a beam. For one air diffuser 200, two device attachments 29 are attached to one main material 1 with fasteners temporarily fastened, and are slid along the groove 2 of the main material 1, It is moved to both sides in the width direction of the air diffuser 200. Then, each device fixture 29 is arranged so that the holding portion 29b is positioned above the frame of the air diffuser 200. In this state, tighten the fastener passed through the base portion 29a. In this way, as shown in FIG. 24, the air diffuser 200 is attached to the main member 1 as a beam so that it is sandwiched between the pair of device fixtures 29 from both sides.

In the frame 100 constructed using the main material 1 as described above, the grooves 2 provided on the mutually opposing sides (first side surface 3) of the main material 1 can be interconnected using various connection aids. This allows the main members 1 to be connected vertically and horizontally. In this case, each of the connecting aids can be attached to any position in the groove 2 extending along the longitudinal direction of the main material 1, and the main material 1 can be formed from a member with a simple structure to an appropriate length. It can be used as You can freely adjust the length of the main material 1 as a beam, the height of the main material 1 as a support, and the installation height of the main material 1 as a beam relative to the main material 1 as a support, so you can adjust the installation surface. The frame 100 can be constructed with suitable dimensions and shapes according to various conditions such as the shape, height, and dimensions of each part.

The main member 1 can be used not only as a beam but also as a support, and the groove 2 can be used to fix it to an installation surface and to connect it to the main member 1 as a beam. That is, the support and the beam can be made of the same material. The invention described in Patent Document 1 above uses standard parts such as columns and rail-like members as components of the mount, and by unifying these standards, it is easy to construct a mount suitable for the form of the installation target. It was technology. In the pedestal structure of this embodiment, the main material 1 of the same shape plays the roles of the "support" and "rail-like member" in Patent Document 1, which further reduces the number of types of parts required to construct the pedestal. , the effort and cost of manufacturing and managing parts can be further significantly reduced compared to the technology described in Patent Document 1.

Another major feature of the frame structure of this embodiment is that the main material 1 is constructed as a member in the shape of a bent plate-like material, and that the main material 1 can be manufactured from metal. So far, the products that have been put into practical use with racks configured with rail-like members as described in Patent Document 1 are those made of resin, at least to the extent that the inventors are aware of. At sites where the frame is required to be constructed of metal to ensure strength and durability, the frame has no choice but to be manufactured using the traditional method of welding metal parts in a factory. Ta. When manufacturing frames using this method, the parts are assembled in advance by welding at a factory and then transported to the site where final assembly is performed. Structural materials are difficult to pack tightly into transportation vehicles, and transportation is costly and time consuming. Moreover, due to the weight of the parts and vibrations during transportation, unreasonable force is applied to the joints between the parts, which tends to cause deformation. To prevent this, strict packaging is required during loading, reducing the time and cost of transportation. It will increase further. Furthermore, the quality of welding tends to be influenced by the skill of the worker performing the welding, the equipment of the factory, etc., and there is also the problem that the quality of the frames varies depending on the supplier.

In the pedestal structure of this embodiment, the main material 1, which is the main component, is formed as a simple linear member, and by providing grooves 2 here, the mount can be constructed by freely combining the main materials 1 with each other. made it possible to do so. The main material 1 is a simple hollow square columnar member, and can be easily manufactured by forming a metal plate by a method such as roll forming. The main materials 1 can be connected to each other using various connecting aids without welding, so when manufacturing a frame, the simple straight main materials 1 are brought to the site in that state, and the connecting aids are used to connect the main materials 1 to each other. All you have to do is assemble it on site using the . Therefore, a large amount of material can be packed into a transport vehicle and transported at low cost and with less effort. Since the main materials 1 are transported without being combined with each other, there is no concern that mechanical loads will be applied to the joints during transport, and packaging and loading are easy. There is no possibility of failure of the frame due to variations in welding techniques.

Moreover, the hollow main member 1 is configured to be divided into a pair of half-split bodies 4 at the second side surface 5. That is, two halves 4 of the same shape are manufactured and combined to form one main material 1. Such a configuration simplifies the manufacturing process of the main material 1 and reduces the manufacturing process. This helps further reduce effort and costs.

Generally, when forming a plate-shaped metal by roll forming, a bending step is required for each bent portion. Therefore, the more bends there are in one type of member, the longer the processing time and the higher the cost. According to the method of manufacturing the main material 1 by combining two halves 4 manufactured in the same shape as in this embodiment, the number of roll forming steps required to manufacture one main material 1 is , the number of steps is sufficient to form the half body 4. In other words, the number of bending processes required to form the half bodies 4 by roll forming is smaller than the number of bending processes required to form the half bodies 4 by rolling. Although an extra step is required for the engaging portion 6 necessary for joining, the number of steps is slightly more than half. Since it is possible to manufacture one main material 1 with two identical half-split bodies 4, when the main material 1 is formed from two half-split bodies 4, the required production line is one piece. Compared to the case where the equivalent main material is formed from sheet materials, the amount required is slightly more than half.

Here, in the gantry structure described in Patent Document 1, it can be said that the rail-like member functionally has a structure that is partially in common with the groove portion 2 in the main material 1 of this embodiment, on the upper and lower sides. However, in the case of the rail-shaped member of Patent Document 1, the shape is different between the upper surface side to which the air diffuser is attached and the lower surface side joined to the support column. Therefore, when trying to make a member of the same shape as the rail-like member made of resin as described in Patent Document 1 from metal, a part (half body 4) having the same shape as the main material 1 of this example is used. The method of manufacturing and combining them cannot be used. Even if the parts are divided into upper and lower parts, parts with different shapes will be produced, so a separate bending process will be required to form each part, and the number of bending processes cannot be reduced. As in this embodiment, only by forming the main material 1 in a vertically symmetrical shape, it is possible to construct the main material 1 with a pair of halves 4 of the same shape, and when manufacturing by roll forming. This makes it possible to simplify the process. Moreover, in the pedestal described in Patent Document 1, the rail-like member and the support column are configured as parts with different shapes, so when attempting to manufacture these by roll forming using metal as a material, the formation of the member corresponding to the support column is difficult. However, additional steps are required, further increasing construction time and costs.
